[U-Boot] [PATCH v4 0/6] Generic file system firmware loader DM

[tien.fong.chee at intel.com]

From: Tien Fong Chee <tien.fong.chee at intel.com>

This patchset contains generic file system loader DM which is very close to
Linux firmware loader but for U-Boot framework. Generic file system firmware
loader can be used load whatever into target location, and then consumer driver
would use it to program whatever, ie. the FPGA. This version mainly resolved
comments from Simon and Anatolij in [v3].
Patch set for sandbox will be sent out separately.

This series is working on top of u-boot-socfpga.git -
